💖 ndctl-disable-region 💖

okay bestie, welcome to the ndctl manual, specifically the disable-region page. yeah it's from the ndctl Manual, but honestly? it's giving ✨main character energy✨ and we're gonna read it together, mwah 🫶

🌸 NAME 🌸

ndctl-disable-region — disable the given region(s) and all descendant namespaces 😭

like, the whole family tree is going down with it, no survivors, periodt.

🎀 SYNOPSIS 🎀

ndctl disable-region <region> [<options>]

that's it. that's the whole vibe. one region (or more, we'll get there) plus your lil options. slay. 💅

🦋 DESCRIPTION 🦋

okay so here's the lore 🧚:

a generic REGION device gets registered for each PMEM range / interleave-set. that's just how it is, that's the setup. no cap.

and LIBNVDIMM? it ships a built-in driver for these REGION devices. iconic of it honestly 👑

and what does that driver do, you ask? bestie it is responsible for:

  • parsing namespace labels 📝
  • instantiating PMEM namespaces for each coherent set of labels ✨

so yeah, the driver is out here doing the absolute most so that your namespaces exist at all. we love a hardworking king. 🔥

💅 OPTIONS 💅

  • <region> — a regionX device name, or a region id number. use it to restrict the operation to the specified region(s). and yes, you can pass the keyword all to indicate the lack of any restriction — but ngl, that's literally the same as not supplying a --region option at all. so like... do with that what you will 🙈
  • -b, --bus= — a bus id number, or a provider string (e.g. "ACPI.NFIT"). restricts the operation to the specified bus(es). and again, the keyword all can be specified to indicate the lack of any restriction — however this is the same as not supplying a --bus option at all. yes bestie, same energy as above, they really said symmetry 💖
